COKE-DISCHARGING APPARATUS FOR VERTICAL RETORTS.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed September 9, 1910. Serial N0.-581,209.

To all whom it may concern:

Be it known that we, SAMI'EL (lumen and JOHN WEST, subjects of the Kingof Great. Britain and Ireland, residing at Olive mount, St. Annes, St.Hele'ns. and The Firs, Park Road, Southport, both in the county ofLancaster, England, have invented certain new and useful Improvements inCoke-Discharging Apparatus for Vertical Retorts, of which the followingis aspecification.

This invention relates to improvements in the construction of a helix orworm discharging apparatus applied for the purpose of discharging thecoke from vertical retorts used in the distillation of coal shale andthe like, and has for its object the construction of the helix or wormin two sections so that one section can be partly rotated on its axis orspindle to such an extent that a free space is made which will permitthe inspection of the retort and a ready access to the retort when it isrequired to be scurfed or cleared from carbon deposits on the interiorof the retort; the scurfing tools being insertcd through the space madebetween the two sections of the worm.

When the Worm is in action for discharg ing the retort, the two sectionsare joined torcther and held together by a catch which can be releasedin a ready manner through an inspection hole provided in the cokechamber.

In order that our 1nvent1on may be readily understood, we shall proceedto describe the same in reference to the accompanying drawings.

Figure 1 shows the worm when divided.

leferring to Figs. ,1 to 5 the worm is made 111 two parts a and b, theparta being free to rei'olve on the shaft or axis 0, but the:

part b is secured to the shaft c. The motion of the shaft 0 when the twoparts aand b are coupled together causes the worm to revolve as thoughit was constructed in one piece.

(Z and ti are lugs cast on the faces of the parts a and Z); c is the eyebearing for the pin (Z which holds the catch f.

is an inspection door in the coke receiving chamber below the wormdischarging apparatus and through which access is made to the worm forthe purpose of releasing or fixing the catch f when it is required toseparate the two sections of the worm, and which. also permits theinspection of the retorts and the insertion of the scurfing tools.

h is a vertical retort to which the improved discharging apparatus isapplied.

WVhat we claim and desire to secure by Letters Patent is In combination,a helix composed of two sections, each of said sections extending,

through a portion only of a complete annulus, whereby there will be aspace formed between the ends of each section and a shaft, one of saidsections aflixed to said shaft and the other of said sections beingrotatably mounted upon said shaft, whereby said other sect-ion may berotated to cause the space formed between its ends to register withthespace formed between the ends of said first section. and means forholdingsaid second section against rotation with one'of its endsengagingone of the ends of said first section to form a continuous helix.

In testimony whereof we have affixed our signatures. in presence of twowitnesses. Y
